Replacing Hallogen by LED

Never used the new boat. But already searching to save energy to help the fridge and pilot.
The main cabin has 9 lights incorporated to the ceiling. That is 9 lights coming on at the flick of the switch. The front cabin has 6 and so one ...reading lights and all.
Using the internet brings many suppliers. Its an easy task to find replacement bulbs at very various prices for apparently the same product.
The question that I cant find is what replaces what as far as luminescense.
Some stores have douzens of lights that are mounted and that we can test. We can also take ours and try them to compare.
Funny thing the Led lights dont seem to glare very far, where the hallogen does.
Has anyone done the exersize to replace with a good result at end.
The 470 2010 has Kando lite 30 degre 12 volt 10 watt capsules
the reading lights are 12 volts 20 .
Picture shows 35mm with 4mm pins

Its a boat discussion to me and it sets out how often I have to re charge the batteries when at anchor or on a mooring.
On our 430 we have changed 1/2 the lights to Led's and left the rest as halogen this allows us to only use a lower discharge of the batteries when not on the mains electric yet we can get lit up like a Christmas tree when on the mains.
If you change to Led's you have to expect reduced light output until technology improves.

Indeed, now the LED are less expensive if u take it from outside, not shops from your country, uses little energy and it has a great light...
The most cheaper way to get your hands on some LED''s are those thate are made in China!!!
